Dynamic systems of concentric ring magnetic domains in a highly anisotropic garnet ferrite film in magnetic fields at infrasonic frequencies

摘要

Dynamic domain structures in a garnet ferrite film with perpendicular anisotropy are investigated in magnetic fields at infrasonic frequencies for the first time. It is revealed that the multidomain film exists in the anger state and that stable dynamic structures with unusual properties are formed in ac magnetic fields at frequencies of 2-3 Hz.
